Streamlining

Streamlining refers to the practice of simplifying code to reduce complexity, remove redundancy, and improve readability and maintainability.

Streamlining often involves replacing verbose constructs with more expressive modern syntax: match expressions instead of switch, arrow functions instead of closures, named arguments to clarify intent, nullsafe operators to flatten nested null checks, and short-circuit assignments with ??=.

Streamlining is distinct from premature optimization: it targets structural and expressive clarity rather than micro-level performance, and its effect is measured by reduced cognitive load for the reader.

<?php

    // Before streamlining
    if ($value === null) {
        $value = computeDefault();
    }

    // After
    $value ??= computeDefault();

?>
